Specification of Letters Patent.

Patented May a, 1909.

Application filed August 22, 1907. Serial No. 389,750.

This invention has reference to improvements in trucks or loading apparatus and has frame of considerable length mounted upon a wheel mounted axles and bolsters, the connections for the tongue or pole to the truck being interchangeable, so that the axles may serve alternately as the front and rear axles of said running gear.

A further object of the invention is to construct a truck having a supporting frame of considerable length, mounted at or near its opposite ends upon wheel supported axles, having bolsters; cross-rods connecting said axles, which are adapted to move endwise and turn the rear axle in a direction opposite to the direction in which the front axle may be turned; truss rods connected at their opposite ends to the bolsters and passing through hangers placed at intervals and depending from the sides of the supporting frame, and to masts adapted to have an interchangeable connection with the opposite ends of each of said holsters, said mast supporting derrick arms and raising and lower mg means.

A further object of the invention, is a truck, a mast revolubly mounted on said truck, raising and lowering means in connection with said mast, mechanism for operating said raising and lowering means, also mounted in connection with said mast and means for limiting the rotating movement of said mast.

For a further and full description of the invention herein, and the merits thereof, and also to acquire a knowledge'of the details of the result, reference is had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modii fication, still the preferred embodiment of the l l l f l l l 1 l l l l l l l l r invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation on a greatly reduced scale of my improved truck; Fig. 2 is a plan view of said truck Fig. 3 is an end elevation of my improved truck, on a somewhat larger scale than is shown in igs. 1 and 2, and in dotted lines the interchangeability of the masts, derrick arm supported ther by and the raising and lowering means and gearing are illustrated; 4 is a partial plan view of the truck, made to substantially the same scale as Fig. 3 and in dotted line shows for its ob ect a truck comprrsmg a supporting the manner of reversing the guy means for I the mast, and also shows the mast in the running gear at its opposite ends, comprising position of being rotated for the purpose of depositing an object on to the supporting frame of said truck; Fig. 5 is a detail spective of the manner of connecting the lower ends of the mast revolubly to the bol-' sters, and fig. 6 is a detail perspective of the mechanism for operating the raising and lowering means, also the support for said mechanism which includes a member for limiting the rotation of the mast to which said support and mechanism aforesaid, is attached.

Like numerals of reference indicate corre sponding parts throughout the figures.

The axles of the running gear are correspondingly referred to as 1, having connected therewith, the ground wheels 2 likewise the bolsters, which are pivotally mounted upon said axles, are correspondingly referred to as 3. To either of said axles may be connected. a tongue 4 which, at one end, has attached thereto, a cross head 5 which is braced by the straps 6 and a convenient mode of attaching the cross head of the tongue to either of said axles is by means of hooks or links 7 attached to the cross head 5 adapted to have a detachable connection with eyes 8 or other equivalent means, secured to the axles as shown. W'ith this form of connection, either end of the truck may be the forward end, likewise either end thereof may be the rear end, it being desirable, at times,'to use opposite ends of said truck as the forward end, owing to the truck being made of considerable length and it being inconvenient at times to swing the truck as would be necessary were the running gear confined to front and rear axles, without provision being made for changing about as above specified.

The axles as shown, have a pivotal connection. with the bolsters, by a suitable king bolt coupling 9 and said axles are connected by the crossed rods which are referred to as 10 one end of each. of said rods being connected at or near the opposite ends of one axle and crossing at a point intermediate, both of said axles, have their opposite ends connected at or near the opposite ends of the opposite axle. Where the rods cross each other, they pass through a loop, eye, or hanger, which I have indicated as 1 1 and which depends from a frame support 1.3, of suitable width, which is secured at its opposite ends to the bolsters 3 and preferably extend beyond said bolsters, as shown. The opposite extended ends of the frame support 13 are suitably braced by means of the cross braces 14 which are connected with the lower opposite corners of said frame support and their opposite ends connected with the bolsters 3, as best seen in Fig. 3 and for bracing the body of the frame support 13, trussrods 15 are provided which are. secured at their opposite ends to the bolsters 3, by being secured to the upper faces thereof, in a suitable manner, and then inclined downwardly as at 16 toward the opposite ends of said truck, said rods are then carried in a horizontal plane parallel with the body of the frame support 13 and pass through or are connected with a plurality of hangers or equivalent members 17, depending from the opposite sides of said frame support, as best seen in Fig. 1.

Through the connection of the crossed rods 10 with the axles 1, 1, the wheels of said. axles, when the axle to which the tongue is attached is swung on its king bolt, will track, owing to the said rods moving endwise, which will force the rear axle to turn at an inclined position, the reverse of the direction in which the front axle is turned, substantially as shown in Fig. 2 and the said rods serve the further purpose of sustaining and holding said axles and prevents canting or side motion, when said truck or the wheels thereof, are moving over irregularities which might have a tendency to cause said axles to oscillate on their pivots. To each of said bolsters 3, upon the opposite sides of the frame support 13, and preferably adjacent to said support, as shown in Figs. 3 and 5, are attached plates 18, from which extend the short studs 19. Adapted to have an interchangeable, as well as a revoluble connection with the studs of said plates are shown davits, which consist, preferably of the upright tubular members or masts 20, which at their lower ends have a telescopic connection with the studs 19, by passing the lower ends of said uprights or masts over the said studs, as shown in Fig. 5. A derrick-arm, indicated as 2]., is shown extending laterally from each of said masts or uprights 20, which at their inner ends, are connected with couplings 22, which are secured to the uprights or masts, at or near their upper ends, as best seen in Fig. 3, and to that portion of the uprights or n ts 20, which project through the coupling" 22, is attached a sleeve or collar 23, providedv with a plurality of eyes 24, with which may be connected the guy-rods 25 and 26, for sustaining the uprights or masts 20 in a vertical position. and allow the same to have a revoluble connection with the studs 19 aforesaid. The lower ends of the guyrods in their present positions, have a detachable connection with. a link 27, connected with a bracket 01' arm 28, secured to the sides of the supporting frame 13, at or near the ends thereof; while the guy-rods 26, at their lower ends, are connected with links 29, which are detachably connected to arms or brackets 30 secured to the ends of the bolsters 3, and each of said guy-rods is provided with turn buckles 31, for maintaining said rods taut and thereby sustaining the uprights or masts in the positions desired. I

ihe outer ends of the derrick-arms 21, are

braced by the diagonal braces 21*, secured at one end with the outer portions of said derrick-arms and to the lower portion of said uprights or masts, as best seen in Fig. 3. The opposite ends of each of said bolsters 3, are provided with the brackets or arms 30 and the forward opposite sides of the opposite ends of the supporting frame 13, have attached thereto, the brackets or arms 28 and the links 27. This duplicate arrangement of the brackets or arms 28 and 30 and the links 27 and 29, at the opposite ends of the truck, together with the duplication of the plates 18 with the studs 19, on the opposite ends of each of the bolsters 3, enables me to provide for an interchangeable connection of the uprights or masts 20, with the said bolsters upon opposite sides of said supporting frame and for bracing the same in the manner heretofore explained, substantially as the same has been shown in dotted lines in Fig. 3. This is very desirable when it is desired to elevate objects from the ground to the truck from either side thereof, as there are times when it would be inconvenient to reverse the position of the truck, and with such an arrangement as I provide, the reverse of the davits may be very quickly'and conveniently made. I provide in connection with said davits, a raising and. lo (ring mechanism, as well as a means, capable of being manually operated for actuating said raising and lowering means. Said raising and lowering means comprise preferably, chains, cables, or equivalent hoisting members 32, which ride over pulleys 33 and 34, journaled respectively at the outer and inner ends of said derric r-arms 21, and above said arms, as best seen in Fig. 3, and said chains, cables, or equivalent hoisting members pass down through slotted openings 35 in the derrick-arms, preferably in the couplings 22, as

shown, and are adapted to be Wound on drums 36, carried on spindles 37, having their opposite ends journaled in arms 38 and 39, integral with semi-circular sections or castings 40 and 41, which are adapted to be bolted to ether on the u' ri hts or masts 2O b b 7 by means of the bolts 42; the location of said sections 40 and 41 being preferably intermediate the connection of the brace 21 with the uprights or masts and the inner ends of the derrick-arms, as shown in Fig. 3. Ch one end of said spindle 37, carrying the druni 36, is a Worm-Wheel 43, meshing with Worin 44 011 a spindle 45, journaled in the arms 46 and 47 of the section 41, heretofore referred to, and adapted to be connected with the outer end of the spindle 45, is a crank 48, lay means of which said druni may be manually operated, although, if desired, some other power means may be applied thereto. To the free ends of the chains, cables, or flexible hoisting ineinbers Si, are attached tongs 49 or some other suitable gripping means or hooks which are capable of being connected to an object which it is desired to elevate to the supporting frame of the truck or to be removed therefrom.

One of the semi-circular sections attached to the uprights or inasts 20, for supporting the gearing for operating the raising and lot, ering ineans, preferahly section 40, pro vided r ith an arm or linger 50 extending out a suitable distance therefrom, ii hich is adapted, when the uprights or niasts have been revolved so as to suing the derrick-anus at right angles to the body of the trucks, as sho'a n in Fig. 3, to engage or conta ith the upper portions of the guy-rod 26. The ohject of such engg'en'ient of the arm 58 with the guy-rod 26, is that when the derrick-arm is SC. ung around into a position hereby the tongs of the chains, cahlcs or hoisting men:- bers 32 v. ill he in a position to be low: cred for the purpose of engaging an object to be placed on the truck or to letter from said truck an ohject to he placed upon the ground or some other suitahle support, said derrick arins ill he stopped in a position at right angles to the hody of said truck. Upon an examination of Fig. 1, the tongue is SllOKl'l'l connected ith the left hand end of the truck and hen so connected, the guy-rod 25 of the mast supported upon that end of the truck, r. ill he connrcted ith the hracket 28, at or near the end of the frame support 13 and the guy-rod 25, for the mast at the opposite end of said truck, still he connected uith a bracket 28, i. hich is attached to the side of the frame support 13, SOIHH/thitt removed from the rear end of said support and between the trso axles as shown. But a hen the tongue is attached to the opposite end of the truck, as shown in dotted lines in Fig. 1, the guy-rod 25, now shown connected with the bracket 28*, will be connected with the bracket 28 at the end of the frame support, and the guy-rod shown at the forward enc, attached to the bracket 28, will be disconnected therefrom and connected with the bracket 28 at the corresponding end of said support. The reason for this is, that the derrick-arms will preferably suing toward the r-ear end hen it is desired to elevate and deposit an object on. the truck, as is shown in Fig. 1, and thus ehenever the tongue is reversed, the guy-rods should be properly connecter for tne purpose of forming a brace for the M f ve davits of said truck, and should alr. ays he so placed as to counterhalanco the s. eight raised ered lxy the chains or cables.

Frorn an examination of the figures. ticularly Figs. 1 and 3, it "-Fiill he seen t spindle 45 supporting the s i orni 44, i ably parallel or in the same plane with the derrick arnis 21, hich places the gearing and the drunis ith which the chains, cables or hoisting rneinlcers 32 are connected, in the open space forincd hy the connection of the uprights 20, the derrick-arms 21 and the brace 21?, in which open space the crankarm 48 may he operated for the purpose of actuating the drunzs as supporting the gearing and drums in any other position that 1 ould create itet n the same or t ie crank-arm and sup-ports for said uprights, and to a certain extent liniit the rotation of the uprights and the su. ing of the derrick-arms.

In the dran ings, the truck has been sh or; n more particularly for use in the handling of railroad rails and has proven very desirable for that purpose, although the said truck is designed for handling any heavy objects, particular y of great length, which may he difficult to handle by hand and unxjieldy in transportation.
